GENERAL DESCRIPTION

earized output voltage directly proportional to measured

temperature. The TC1023 has a temperature measure-

ment range of – 20 C to +100 C. Its output voltage is

directly calibrated in degrees Centigrade (i.e., V

10mV/ C x Temperature C). An external pull-down resis-

tor to a negative voltage source is required for temperature

measurement below 0 C.

– 20 C to +125 C, and operates with a single supply. It has

the same output voltage slope with temperature as the

TC1023 (10mV/ C). The output voltage range is 100mV at

– 20 C to 1,750mV at +125 C. Both devices have a chip

enable input that reduces supply current to 1 A (typical)

when pulled active high. In this state, the output defaults to

a high resistance allowing an external reference voltage to

be directly connected for A/D calibration.

make the TC1023/1024 suitable for a wide range of gen-

eral purpose temperature measurement applications.

... PRECISION TEMPERATURE-TO-VOLTAGE CONVERTERS WITH SHUTDOWN MODE DETAILED DESCRIPTION A plot of output voltage versus temperature for both the TC1023 and TC1024 appears in Figure 5. The TC1023 can be used with single power supply to measure temperatures from 100 C. A pull-down resistor (R1 in Figure 1) must be added from the output pin to the negative power supply for measuring temperatures less than 0 C ...
